Specification forming part of Letters Patent No. 14 6,837, dated January 27, 1874 application filed December 20, 1873.

To all whom it may concern.'

Be it known that I, J oEN X... MILLER, of Chester, in the county of Delaware andState of Pennsylvania, have invented a new and Improved Sash-Fastener, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a side elevation of a window-,sash with my improved fastener applied thereto, guided by the window-frame, which is shown in vertical section on the line c c, Fig. 2; and Fig. 2 is a horizontal section ofmy window frame and sash on the line :n m, Fig. 1.

Similar letters of reference indicate correspondin g parts.

Myinvention relates to improvementsin sashfasteners, by which the sash is retained at any desired point, so as to exclude air, dust, and moisture, prevent rattling, and lock the sash securely in position when closed.

My invention consists in providing the window-sash at both sides with triangular recesses, `into which strong ban d-springs are placed, with forward -projecting rollers attached thereto, which rollers bear against one guide-strip of the window-frame, so as to hold the sash by its friction on the other guide-strip in any postion in which it is placed.

For locking the sashin closed position, so as to prevent its opening from the outside, small catches are attached to the lower parts of the outer` guide-strips, which catches engage a corresponding recess of the sash, while the necessary play of the sash for engaging and disengaging it from the catches is obtained by re cesses at both sides.

In the drawing, A represents the windowsash, and B the window-frame, which guides the sash by a rabbet or groove of corresponding size between the projecting strips A. Sash A is provided at both sides with triangular recesses b, with a central extension toward the inside, in which the sash-fastener C is inserted. The fastener C consists of a strongband-sprin g, d, with a metallic` frame, e, attached centrally thereto, in which roller j' turns. The ends of spring d extend into the oblique angles of trian gular recess b,and are irmly retained therein, while frame e and roller f project through the front extension of recess b beyond the sash, so as to bear against the guide-strip a and force `the outer side of sash A against the opposite y strip a. The friction of the sash against the guide-strip a produces its retention in any re-` quired position in which it is raised or lowered, while its close contact against the outer strips prevents the admission of air, dust, and moisturo.

For the purpose of locking the sash firmly in position after it is closed, so as to prevent its being raised from the outside, I apply to the outer guide-strips a, near their lower ends, small downwardly-proj ecting catches g, which t into l recesses g', of similar shape, at the outside of sash A. Recesses h, the depth of` which is equal to the thickness of the catches g, 'are cut along the side edges of sash A, which is also y beveled at its lower outer edge `below recesses g', so that the sash, when pulledinwardly and raised by a knob or button at the inside, is carried against the inner guide-strips andreleased from catches g for raising it. g

Heavier sashes may, besides the friction-rollers and springs, be provided in the usual manner with cords, pulleys, and'weights, the pres ence of the spring serving then only to pref` vent rattling and make them iit tightly to the frame. Instead of the weight, catches or ratchets for retaining the sashes in different positions may be employed. y i

The tight closing of the spring-rollers makes it very useful for cars, ship-work, pilot-houses, and other piuposes, as not only all rattling is avoided, but, moreover, a thorough exclusion of the moisture and water is obtained. For the latter purpose an angle of the sill maybe used in connection with an .overlapping plate at the bottom of the sash, by which the rising of the moisure from below is prevented. The

top and bottom sashes may also overlap and lock each other by suitable catches and plates, the spring action of the roller and the play of the rabbeted sashes allowing their ready separation for throwing them open.

I am aware that it is not new to use a roller i and spring in connection with a window-sash and casingfor the purpose specified by me, and therefore I do not desire to claim said roller and spring, broadly.

Having thus described my invention, I claim as new and desire to secure by Letters Pat` lent@ l. As un improvement in friction snsh-ustl catches r/ for locking the sash in closed posieners, the eombuaton. of sash A, havmg rnon to prevent the Opening from the outside, angular side recesses I), Wxth spring-rollers d e and give it sufeent play for raising it, as set fand projecting' guide-strips a,v of sash B, arforth.

lmlged substantially as and for the purpose described.
